3. Nitrocarburizing

Carbonitriding is a method of simultaneously infiltrating the surface of the workpiece into carbon and nitrogen to form a carbonitrided layer. Using this method, the mold has small deformation, high permeation speed, low cost, and the surface of the plastic mold treated by this method. It has extremely high hardness, high anti-adhesion, abrasion resistance, seizure resistance and scratch resistance, and the service life of the mold can be increased by 2-4 times. However, after gas nitrocarburizing, the mold often deforms due to the expansion of the surface compound, so it is not suitable for precision plastic molds.
